ATMOS ENERGY CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
June 30, 2005
1. Nature of Business
      Atmos Energy Corporation (“Atmos” or “the Company”) and its subsidiaries are engaged primarily in the natural gas utility business as well as certain nonutility businesses. Through our natural gas utility business, we distribute natural gas through sales and transportation arrangements to approximately 3.2 million residential, commercial, public-authority and industrial customers through our seven regulated natural gas utility divisions, in the service areas described below:
     
Division   Service Area
     
Atmos Energy Colorado-Kansas Division
  Colorado, Kansas, Missouri (3)
Atmos Energy Kentucky Division
  Kentucky
Atmos Energy Louisiana Division
  Louisiana
Atmos Energy Mid-States Division
  Georgia (3) , Illinois (3) , Iowa (3) , Missouri (3) , Tennessee, Virginia (3)
Atmos Energy Mississippi Division (1)
  Mississippi
Atmos Energy Mid-Tex Division (2)
  Texas, including the Dallas/Fort Worth metropolitan area
Atmos Energy West Texas Division
  West Texas
 
(1)   The name of this division was changed from the Mississippi Valley Gas Company Division in April 2005.
 
(2)   Acquired in October 2004.
 
(3)   Denotes locations where we have more limited service areas.
      As further described in Note 3, on October 1, 2004, we completed our acquisition of the natural gas distribution and pipeline operations of TXU Gas Company (TXU Gas). The TXU Gas operations we acquired are regulated businesses engaged in the purchase, transmission, storage, distribution and sale of natural gas in the north-central, eastern and western parts of Texas. We also acquired a system consisting of 6,162 miles of gas transmission and gathering lines and five underground storage reservoirs, all within Texas. As a result of the TXU Gas acquisition, on October 1, 2004, we created the Atmos Energy Mid-Tex Division, which provides gas distribution services to our approximately 1.5 million residential and business customers in Texas, including the Dallas/Fort Worth metropolitan area. We also created the Atmos Pipeline — Texas Division to manage and operate the TXU Gas pipeline and storage operations we acquired.
      In addition, we transport natural gas for others through our distribution system. Our utility business is subject to federal and state regulation and/or regulation by local authorities in each of the states in which the utility divisions operate. Our shared-services division is located in Dallas, Texas, and our customer support centers are located in Amarillo, Texas, and Metairie, Louisiana. In addition, on April 1, 2005, we took over the operations of a Waco, Texas customer support center, and all call center services formerly provided by TXU Gas under a transitional services agreement were terminated. We intend to close the purchase of the related assets on October 1, 2005 for approximately $1.7 million.
      Our nonutility businesses include our natural gas marketing operations, our pipeline and storage operations and our other nonutility operations which are provided in 22 states. These operations are either organized under or managed by Atmos Energy Holdings, Inc. (AEH), which is wholly-owned by the Company.
      Our natural gas marketing operations are managed by Atmos Energy Marketing, LLC (AEM), which is wholly-owned by AEH. AEM provides a variety of natural gas management services to municipalities, natural gas utility systems and industrial natural gas customers, primarily in the southeastern and midwestern states

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
and to our Colorado-Kansas, Kentucky, Louisiana and Mid-States divisions. These services consist primarily of furnishing natural gas supplies at fixed and market-based prices, contract negotiation and administration, load forecasting, gas storage acquisition and management services, transportation services, peaking sales and balancing services, capacity utilization strategies and gas price hedging through the use of derivative instruments.
      Our pipeline and storage operations consist of the operations of our Atmos Pipeline — Texas Division, a division of Atmos Energy Corporation, and of Atmos Pipeline and Storage, LLC (APS), which is wholly-owned by AEH. The Atmos Pipeline — Texas Division was purchased from TXU Gas and transports natural gas to the Atmos Energy Mid-Tex Division, transports natural gas to third parties and manages five underground storage reservoirs in Texas. Through APS, we own or have an interest in underground storage fields in Kentucky and Louisiana. We also use these storage facilities to reduce the need to contract for additional pipeline capacity to meet customer demand during peak periods.
      Our other nonutility businesses consist primarily of the operations of Atmos Energy Services, LLC (AES) and Atmos Power Systems, Inc., which are wholly-owned by AEH. Through AES, we provide natural gas management services to our utility operations. These services, which began on April 1, 2004, include aggregating and purchasing gas supply, arranging transportation and storage logistics and ultimately delivering the gas to our utility service areas at competitive prices. Through Atmos Power Systems, Inc., we construct gas-fired electric peaking power-generating plants and associated facilities and may enter into agreements to either lease or sell these plants.
2. Unaudited Interim Financial Information
      In the opinion of management, all material adjustments (consisting of normal recurring accruals) necessary for a fair presentation have been made to the unaudited consolidated interim-period financial statements. These consolidated interim-period financial statements and notes are condensed as permitted by the instructions to Form 10-Q and should be read in conjunction with the audited consolidated financial statements of Atmos Energy Corporation in its Annual Report on Form 10-K for the fiscal year ended September 30, 2004. Because of seasonal and other factors, the results of operations for the three and nine-month periods ended June 30, 2005 are not indicative of expected results of operations for the fiscal year ending September 30, 2005. Further, the impact of the TXU Gas acquisition on the statement of cash flows is reflected in the acquisitions line item; therefore, the net changes in operating assets and liabilities will not reflect balance sheet changes attributable solely to that acquisition.
Significant accounting policies
      Our accounting policies are described in Note 2 to our Annual Report on Form 10-K for the year ended September 30, 2004. There were no significant changes to our accounting policies during the nine months ended June 30, 2005.
Stock-based compensation plans
      We have two stock-based compensation plans that provide for the granting of incentive stock options, nonqualified stock options, stock appreciation rights, bonus stock, time-lapse restricted stock and performance-based restricted stock units to officers and key employees: the 1998 Long-Term Incentive Plan and the Long-Term Stock Plan for the Mid-States Division. Nonemployee directors are also eligible to receive such stock-based compensation under the 1998 Long-Term Incentive Plan. The objectives of these plans include attracting and retaining the best personnel, providing for additional performance incentives and promoting our success by providing employees with the opportunity to acquire common stock.

6


ATMOS ENERGY CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
      As permitted by Statement of Financial Accounting Standards (SFAS) 123, Accounting for Stock-Based Compensation , we account for these plans under the intrinsic-value method described in Accounting Principles Board (APB) Opinion 25, Accounting for Stock Issued to Employees . Under this method, no compensation cost for stock options is recognized for stock-option awards granted at or above fair-market value. Awards of restricted stock are valued at the market price of the Company’s common stock on the date of grant. The unearned compensation is amortized to operation and maintenance expense over the vesting period of the restricted stock. As discussed below, beginning October 1, 2005 we will account for our stock-based compensation in accordance with SFAS 123 (revised), Share-Based Payment .
      Had compensation expense for our stock options issued under the Long-Term Incentive Plan been recognized based on the fair value on the grant date under the methodology prescribed by SFAS 123, our net income and earnings per share for the three and nine-months ended June 30, 2005 and 2004 would have been impacted as shown in the following table:
                                   
    Three Months Ended   Nine Months Ended
    June 30   June 30
         
    2005   2004   2005   2004
                 
    (In thousands, except per share amounts)
Net income — as reported
  $ 4,486     $ 4,765     $ 152,587     $ 92,611  
Restricted stock compensation expense included in income, net of tax
    542       384       1,514       580  
Total stock-based employee compensation expense determined under fair-value-based method for all awards, net of tax
    (676 )     (651 )     (2,114 )     (1,428 )
                         
Net income — pro forma
  $ 4,352     $ 4,498     $ 151,987     $ 91,763  
                         
Earnings per share:
                               
 
Basic earnings per share — as reported
  $ 0.06     $ 0.09     $ 1.96     $ 1.79  
                         
 
Basic earnings per share — pro forma
  $ 0.05     $ 0.09     $ 1.95     $ 1.77  
                         
 
Diluted earnings per share — as reported
  $ 0.06     $ 0.09     $ 1.94     $ 1.78  
                         
 
Diluted earnings per share — pro forma
  $ 0.05     $ 0.09     $ 1.94     $ 1.76  
                         
      At June 30, 2005, there were 300 options outstanding under the Long-Term Stock Plan for the Mid-States Division, all of which were fully vested. Because of the limited activities of this plan, the pro forma effects of applying SFAS 123 would have less than a $0.01 per diluted share effect on earnings per share.
Regulatory assets and liabilities
      We record certain costs as regulatory assets in accordance with SFAS 71, Accounting for the Effects of Certain Types of Regulation , when future recovery through customer rates is considered probable. Regulatory liabilities are recorded when it is probable that revenues will be reduced for amounts that will be credited to customers through the ratemaking process. Substantially all of our regulatory assets are recorded as a component of deferred charges and substantially all of our regulatory liabilities are recorded as a component of deferred credits and other liabilities. Deferred gas costs are recorded either in other current assets or liabilities and the regulatory cost of removal obligation is separately reported.
